An apparatus for adjusting a tilt angle of a plurality of slats in a window blind is disclosed. The window blind includes a headrail having disposed therein a shaft that causes the tilt angle of the slats to be adjusted when the shaft is rotated. The apparatus comprises a first bevel gear, a second bevel gear in mechanical communication with the first bevel gear and coupled with the shaft, and a motor coupled to the shaft. Actuation of the first bevel gear causes a corresponding rotation of the shaft to adjust the tilt angle of the slats, and actuation by the motor causes a rotation of the shaft to adjust the tilt angle of the slats.

An anti-ballistic protection system for protecting a space in a building or vehicle comprising a protective blind including plurality of slats or a sheet of a laminated material having a plurality of layers of lightweight, flexible, ballistic resistant material which are secured together using a glue, heat weld, or stitching. The system may include an automated control system operably configured to cause a change in state of the blind from a retracted state to a protective deployed state, which may include a sensing system operably configured to detect a threatening event, wherein the sensing system upon sensing the threatening event triggers the blind to transition from the retracted state to the deployed protective state such that in the protective state, the blinds are adapted to be resistant to penetration by high-speed ballistic objects such as bullets.

The invention relates to a slat (1) or a slatted roof (20) or a slatted window, comprising a light-permeable sheet-like covering element (2) having a longitudinal extent and width (b), wherein the width (b) is less than the longitudinal extent, and having an axis of rotation (5) which runs along the longitudinal extent of the slat (1) in order to pivot the slat (1) between a closed position and an open position. In order to allow a particularly flexible variation of the incoming sunlight entering a room (22) situated below the slatted roof (20) and in order to be able to set the desired temperature, climate control and brightness conditions in the room in a targeted manner, it is proposed that the slat (1) has at least one light-impermeable sheet-like shading element (6) having a longitudinal extent and a width (h), in which the shading element extends with the longitudinal extent thereof along the longitudinal extent of the covering element (2), that it is arranged with a first longitudinal side (6a) on the covering element (2) and projects with a second longitudinal side (6b), opposite the first longitudinal side (6a), from the covering element (2), wherein the at least one shading element (6) is arranged in the areal extent thereof at an angle () to the areal extent of the covering element (2). (FIG. 10).

An obstruction detection system for motorized window shades is presented having a motor, shade material, a bottom bar, and a motor controller having a microprocessor. The microprocessor is configured to detect when an obstruction has been encountered when closing the motorized window shades. When an obstruction is detected, the microprocessor stops lowering the shade material and the bottom bar thereby preventing further damage or destruction. The system may also be used to report when an unexpected obstruction has been detected.

The present disclosure relates to an electronic venetian blind, the electronic venetian blind, as a first invention, including: a first transparent conductive film layer; a plurality of unit electrochromic layers stacked on the first transparent conductive film layer, arranged separated from each other; and a plurality of second transparent conductive film layers each stacked on the plurality of unit electrochromic layers and independently applying current thereto.

We disclose a window blind which purifies the surrounding air using electrostatic interactions. The window blind includes slats which may have a strip of positively charged material, a strip of negatively charged material, or both attached to the top of the slat. In some embodiments, the positively charged material and the negatively charged material are attached to alternating slats. In other embodiments, the positively charged material and the negatively charged material are attached to the top of the same slate with a strip of insulating material positioned between them. The window blind may include an air-moving device which moves air past the slats so that dust particles with either a net positive charge or net negative charge may be attracted to the oppositely charged material on the slat. The air-moving device may be a vacuum or a fan. The positively and negatively charged materials may be removeable for cleaning.
